Triggers of Swimmer's Ear

Swimmer's ear occurs when water becomes trapped inside. This can cause pain, inflammation and infection.

The American Academy of Otolaryngology -- Head and Neck Surgery says potential triggers include:

• Spending time in a moist environment, such as swimming, bathing or showering.
• Exposure to bacteria, as may be found in hot tubs or polluted water.
• Buildup of hairspray or hair dye inside the ear.
• Injuring skin inside the ear canal.
• Development of conditions inside the ear canal, including eczema or seborrhea.
